Overview
The LC75343M is an electronic volume system that can
control the volume, balance, 2-band equalizer, super bass,
and input switching functions by serial data input.
changing the capacitor capacitance.
Features
• On-chip buffer amplifier cuts down number of external
components
• Low switching noise generated by on-chip switch due to
use of silicon gate CMOS process
• On-chip reference voltage circuit for analog ground
• Controls performed with serial data input (CCB)
Functions
• Volume: 0 dB to –78 dB (1-dB step) and –∞ (64
positions)
0 dB to –50 dB (1-dB step), –50 dB to –70 dB
(2-dB step), –70-dB to –78 dB (4-dB step)
Balance function with separate L/R control
• Treble: ±10-dB control in 2-dB steps is possible.

Usage Cautions
• Upon power application, the internal analog switch status is undefined. Use an external countermeasure such as
muting until data is set.
• When performing initial setting after applying power, send the initial setting data for the left and right channels
prior to canceling mute.
• To ensure that the high-frequency digital signals sent to the CL, DI, and CE pins do not spill over to the analog
signal block, either guard these signal lines with a ground pattern, or perform transmission using shielded wires.
